ANIMAL-STANCHION.

Specification of Letters Patent.

Application filed July 29, 1918. Serial No. 247,297.

chions, of which the following is a specification.

My invention relates to improvements in animal stanchions.

Important objects of the invention are to provide a stanchion of the above mentioned character having; arms 'with the middle portions of the arms out of the transverse vertical plane of the lower portions thereof, when the arms are closed and within the transverse vertical plane when opened; means to automatically cause the stanchion to assume a predetermined transverse position when removed therefrom; adjustable means for supporting the arms of the stanchion, to shift themforwardly or rearwardly; means for adjusting the arms of the stanchion toward and away from each other when closed; simple and reliable means for opening and closing the stanchion and servin to lock the same in the closed and'opene positions; flexible rotatable sup porting means at one end of the stanchion anal flexible anchoring means at the other on 1 Other objects andadvantages of the invention willbe apparent durlng the course [of the vfollowing description.

ffIn the accompanying drawings, forming a part of this specification and in which like a numerals are employed to designate like parts throughout the same,

Fig. 9 is a similar view taken on line 9-9 of Fig. 4, and,

Fig. 10 is a detail horizontal section taken on line 10-10 of Fig. 8.

In the drawings wherein for the purpose Patented Sept. 2, 1919.

of illustration is shown a preferred embodiment of my invention, the numeral 15 designates my stanchion as a whole, comprising upstandmg tubular arms 16, as shown. Each arm 16, as more clearly shown in Fig.

2, embodies a lower vertical portion 17, and: the arm is bent at a point near its center, as

shown at 18, providing an upper portion 19, arranged forwardly of the lower portion 1 When the arms 16 are in the closed position, the upper portions 19 are arranged in a transverse vertical plane in advance of the transverse vertical plane of the lower portions 17 and when the arms 16 are swung to the open position, the upper and lower portions thereof are arranged in the same ver--.

tical transverse plane. Arranged near and beneath the lower ends of the arms 16 is a U-shaped yoke or member 20, provided at its ends with vertical reduced portions 21, shown more clearly in Figs. 8 and 10. These reduced portions 21 are cylindrical and are pivoted within the lower ends of the tubular arms 16. The extensions 21 are provided with diametrically oppositely arranged segmental openings 22, receiving transverse pins 23, attached to the lower ends of the arms 16. It is thus apparent that each arm has a pivotal connection with the U-shaped member or yoke 20. a

A flexible anchor 24, such as a chain, is

the curb 26, of the floor of the stall. F or- .wardly of the curb 26 is a manger 27,. and

rearwardlyof this curb' is a litter gutter 28, as is well known.

In Fig. 2" I have shown adifi'erent form member 29 is provided,- aving an eye 30,

swiveledthereto for connection with the flexible anchor 24. One endef the trans versemember 29 projects intolan elbow 31,

and is bolted or riveted thereto. One arm 16 is pivoted withinthe upper end of the elbow 31 and is provided with .theitrans-r verse pin or bolt 23, shown clearly in CFi'glf 1Q. The .pin or bolt 23] projects through i and "operates 1 within segmental slots 82,

whereby the arm 16 is free-to -turn, ;as explained'in connection with Fig. 1. The numeral'33 designates a T-coupling, ;and the transverse member '29 isgilongitudinallyad- I 'justably mounted within thehorizontal portion of the T-coupling. This T-ooupljing is I yprovided withiopenings-forthe reception of 'f a bolt 34, adapted for insertion within a se- Llectedopening'35. 'The vertical, portion of the T-coupling 33 pivotally receives the loweraendofthe other arm 16. -This arm carries the transverse bolt or pin23, operatting f within ,diametrically oppositely ar- 1 ranged slots 36, for effecting. a pivotal con nectionl-between the arm '16' and the T-cou- ,ends of the arms 16 may-be and away from each other.

It is: thus apparent thatradjustable means. are provided whereby the lower shifted toward 7 v r Disposed, at, thegu'pper ends of the arms 38 i(see;:l:lig;, projectinginto the upper ends of thetubular arms 16 and held therein jand 41, byv bolts 43' or thelike.

The cranks; 'ihave-theirupper ends forked, providing ears or knuckles 40,,and crank extensions 41. r V -Arranged between the elements 40 an'd'41 are horizontalsupporting arms 42,lwhich are -;horizontally 'rangularly adjusted for shifting the entire stanchion forwardly-r and rearwardlywith respect to the elements 40 7' ingsl' are; adapted -for-the reception of, a
